Provided are a beam forming method and device. The method includes: a base station receiving an uplink feedback signal from a terminal, and recovering one or more channel parameters from respective transmitting antennas of the base station to the terminal according to the uplink feedback signal; and the base station adjusting a transmitting phase of a data signal to be transmitted according to the one or more channel parameters from the respective transmitting antennas to the terminal, and forming a beam in a specific direction. Through the present invention, a base station accurately adjusts a transmitting phase of a data signal to be transmitted according to one or more channel parameters fed back by a terminal, thereby being able to achieve accurate beam forming and locating, and also being able to simplify and even omit the real-time phase calibration of the interior of a device and antenna feeder engineering, achieve a higher beam forming gain for various antenna modes, and facilitate achieving a multilayer multi-user operating mode in an LTE. |
